The classic oceanliner look of Disney does draw the eye. I’ve heard when onboard other ships when docked.
But, yes, new ships and their hull art (more than there giant size) are making the cruise world more colorful. The days of just boring, solid white hulls are giving way to Wayland’s whales on NCL Bliss or the flowing-hair Princess.
Dream is my least favorite interior. (Haven’t done Wish). While her twin, the Fantasy offers a beautiful peacock carpet in the atrium. The adult District in both is rather hodgepodge. But the tile bathroom murals there and in Cabanas are what I would expect from Disney.
Some ships I have been on are too 1980s Las Vegas casino for my tastes. MSC in particular. And I am not a fan of the shopping mall feeling of the “atrium in Royal’s Oasis Class, but do appreciate Central Park and the Aqua Theater. You can drop me on any Princess ship and I feel it could be any of their other ships, just differentiated by capacity. But I still enjoy their more classic atrium.
I liked your original post and encourage you to enjoy the happiness of trying DCL, while realizing it wasn’t what you expected from Disney, nor is it what you want from cruising. Just think if this had been your first cruise; you might never have taken another cruise.
Keep having fun and wonderful vacations!
